In order to obtain the stem diameter,height,sweep and to accelerate the automatic measurement for trees,a automatic me- asurement system is developed based on digital image processing. The measurement system mainly consists of an image capturer, a viewing angle adjustor, two calibration rods and an adjustable vertical staff and a notebook PC computer.

The result of analyzing the base content revealed that only the sequences from Buxus bobinieri have GC bias, especially at the third base of codes, and the GC content is more than 70%. All of molecular phylogenetic trees, based on the Beyesian, MP, and NJ methods, consisted of three major clades. Four sequences from Ceratophyllum demersum were grouped into a monophyletic clade (subfamily Ⅱ). Two sequences out of Trochodendron aralioides nested in subfamily Ⅲ. Another three sequences from Kingdonia uniflora interspersed among different subclades of subfamily Ⅰ.
用贝叶斯法、最大简约法和邻接法构建的CHS基因的分子系统树均由3个主要分支构成,其中一个分支由来自金鱼藻的4个序列聚在一起构成了subfamily Ⅱ,来自昆栏树的2个序列聚在一起网接于subfamily Ⅲ中;来自独叶草的3个序列分散于同一亚家族(subfamily Ⅰ)的不同分支中;而多数种的序列分散在相距较远的两个分支中,构成了两个主要的亚家族subfamily Ⅰ、subfamily Ⅲ。

In order to analyze the airborne LiDAR data corresponding to single trees and stand heights in the forestry area, we set up samples to measure tree heights of Alnus formosana, Cryptomeria japonica, and Chamaecyparis formosensis in the Alishan area. We build the Canopy Height Model based on the data from the airborne laser scanning system. Single Tree heights were estimated by averaging the CHM values within a 0.5m radius, and six different sizes of sample stands (5×5, 10×10, 12.5×12.5, 15×15, 17.5×17.5, and 20×20) were set up to extract the average heights within the area as the calculated value.
